Aviation NOx emissions under the spotlight
Future EU measures to curb aviation nitrogen oxide (NOx) emissions should address those produced outside the take-off and landing cycle, according to a report to the European Commission. The national emissions ceilings directive - which covers aviation pollution only during take-off and landing - requires the Commission to report this year on how aircraft flying above 1000m contribute to acidification, eutrophication and the formation of ground level ozone. The consultancy report concludes that this share of NOx emissions has a "small but significant" impact on European air quality. See report.
